Thanks guys.
The last time I was on the dyno I got it all tuned with the 2.93 then swapped the 2.8. We retuned, A/F was very close and the 2.8 lost some gained some through out. No real gain, more lose really. ???
I love having a 2.93 and making 499.1 RWHP and running 122 traps!!!! (before the port)
